‘Big Bang Theory’ Star Kaley Cuoco Shares Sweet Photo With Boyfriend Karl Cook, Dog Rex On Instagram

“The Big Bang Theory” star Kaley Cuoco just can’t get enough of her boyfriend, Karl Cook.

Just recently, the actress shared an adorable photo of her and the equestrian cuddling in bed with Cuoco’s dog, Rex. This is not the first time that the actress posted a sweet snap of her man. A week ago, the actress joked that she can’t choose between Cook and her bulldog.

The self-confessed animal lover has also been actively sharing photos of her pets. Her ongoing collaboration with Paw Works helped change the lives of shelter animals in some parts of the United States. The organization aims to give shelter pets their permanent homes.

Meanwhile, Cuoco celebrated her 31st birthday last week in the company of her boyfriend. The couple went to Craig’s restaurant in California, according to Just Jared.

Last year, Cuoco celebrated her big day with vegan food, as part of her goal to become healthier. While speaking with Shape, Cuoco admitted that she sometimes feels the need to buy jeans in three sizes because she is unsure whether or not she could maintain her weight. “I’m the type of girl who’s always had to buy jeans in three sizes because I never know what my body is going to do from one day to the next,” she said.

But that doesn't mean she doesn't put in effort to keep her body toned and fit. The actress also engages in physical activities, including horseback riding. “Horseback riding is why I’m so centered, especially in this business. I wouldn’t have my career without it. It doesn’t sound like a lot, but I lost six pounds in the last three months. That’s a whole jeans size, and we all know how good that feels,” she said.
